Answer:

a= $-3\frac{2}{3}$ or ≈ -3.66

Step-by-step explanation:

-(3a+4)=7

-3a-4=7

Add 4 to both sides

-3a=11

Multiply both sides by -1

3a= -11

Divide both sides by 3

a= $-3\frac{2}{3}$

Answer:

16 pencils and 17 glue sticks

Step-by-step explanation:

X=pencils

Y=glue sticks

X+Y=33

1.50X+2Y=58

times ten to get whole numbers

=15X+20Y=580

same for e1

=10X+10Y=330

15X+20Y=580

10X+10Y=330

elimination mthd

150X+200Y=5800

150X+150Y=4950

50Y= 850

Y=17

X+17=33

X=33-17

Answer:

A. -2

B. -10

Step-by-step explanation:

Given the equation of the line

$y=\dfrac{1}{2}x-1$

Its slope is $\frac{1}{2}.$

A. Perpendicular line has the slope m, for which

$\dfrac{1}{2}\cdot m=-1\Rightarrow m=-2$

B. The equation of the perpendicular line will be in the form

$y=-2x+b$

This line passes through the point (-6,2), substitute its coordinates into the equation:

$2=-2\cdot (-6)+b\\ \\2=12+b\\ \\b=2-12\\ \\b=-10$

So, y-intecept is -10.

An international company has 23,200 employees in one country. If this represents 26.7% of the company's employees, how many empl

omeli [17]

Answer:

Total number of employees = 86,891 employees

Step-by-step explanation:

Let

x = total number of employees

26.7% of x = 23,200

26.7/100 * x = 23,200

0.267 * x = 23,200

0.267x = 23,200

x = 23,200/0.267

x = 86,891.385767790

approximately 86,891 employees

Total number of employees = 86,891 employees
